单选题 The Africans' interest is to guard preferential export rules enshrined in the temporary African Growth and Opportunity Act, passed by Congress in 2,000. Tariff-free exports of some 6,000 goods from Africa to the United States are boosting trade and investment in southern Africa. Lesotho's fast-growing textile industry depends almost entirely on Chinese investment in factories to make clothes for sale in the United States. The region also wants more access to America's markets for fruit, beef and other agricultural goods. American interest lies mainly in South Africa, by far the largest economy in the region. Services account for 60% of its GDP, and it increasingly dominates the rest of Africa in banking, information technology, telecom, retail' and other areas. Just as British banks, such as Barclays, have moved their African headquarters to South Africa over the past year, American investors see the country as a platform to the rest of the continent. Agreeing investment rules and resolving differences on intellectual property rights are the most urgent issues. American drug firms want to be part of the fast expansion in South Africa of production of anti-retroviral drugs, used against AIDS. By 2007 South Africa alone expects 1.2m patients to take the drugs daily. The country might be the world's biggest exporter of anti-AIDS drugs within a few years. Striking a bilateral deal now should make American investments easier. But Mr. Zoellick's greater concern is for multilateral trade talks that stalled in Cancun, Mexico, in September. Alec Erwin, his South African counterpart, helped to organize the G20 group of poor and middle-income countries that opposed joint American-EU proposals there; he is widely tipped to take over as head of the World Trade Organization late next year, and would be a useful ally. So Mr. Zoellick is trying to charm his African partner by agreeing to drop support for most of a group of issues (known as "Singapore" issues) that jammed up the talks at Cancun, and were opposed by poor countries; he says he also favors abolishing export subsidies in America--though only if Japan and the EU agree to do the same. That would please African exporters who say such subsidies destroy markets for their goods. Mr. Zoellick's efforts to make more friends may be paying off. Even though America has treated Africa very shabbily on trade in the past, Mr. Erwin hints it is easier doing business with America than with Europe or Japan. A small sign, but perhaps a telling one.

单选题Real policemen hardly recognize any resemblance (类同之处)between their lives and what they see on TV--if they ever get home in time. There are similarities, of course, but the cops(警官) don't think much of them. The first difference is that a policeman's real life revolves round the law. Most of his training is in criminal law. He has to know exactly what actions are crimes and what evidence can be used to prove them in court. He has to know nearly as much law as a professional lawyer, and what is more, he has to apply it on his feet, in the dark and rain, running down an alley after someone he wants to talk to. Little of his time is spent in chatting to scanty-clad ([穿衣不多的) ladies or in dramatic confrontations with desperate criminals. He will spend most of his working life typing millions of words on thousands of forms about hundreds of sad, unimportant people who are guilt or not--of stupid, petty crimes.

单选题Even plants can run a fever, especially when they're under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away--straight up. A decade ago, adapting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest (害虫) problems. Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spot-spray, using 40 to 70 percent less pesticide than they otherwise would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States, "says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks? remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.
